Changing the remote controller

mode

When you use any Integra/Onkyo products other

than the NAC-2.3 in the same room, the

operations made with the NAC-2.3’s remote

controller may also cause the other Integra/Onkyo

products to operate. To avoid this, you can change

the remote controller mode both for the NAC-2.3

and its remote controller choosing from three

modes (1, 2 or 3).

To change the remote controller mode for the

remote controller, hold the Standby button on the

remote controller and press the Select button, then

release these buttons simultaneously. Within 5

seconds after releasing the buttons, enter the

appropriate mode (1, 2 or 3) using the numeric

keys. The default mode is 1 for both the remote

controller and NAC-2.3.

After changing the remote controller mode, make

sure that the remote control “Remote ID code” on

the NAC-2.3 is set to the same mode as the remote

controller. (see Page 57)

ADJUSTMENT & CONFIRMATIONS OF OPERATIONS

ADJUSTMENT OF FREQUENCY

a) Turn C702 CCW to set minimum position before POWER ON.

b) Set the frequency at P702 to 32768Hz by adjusting C702 under the condition of no input and no load,

immediately after POWER ON.

c) After 4 ~ 6 minutes of heat running, re-adjust by following b.

OPERATIONS OF SPEAKER RELAYS

The relay shall be ON about 5 seconds after POWER is ON and shall be OFF immediately after

POWER is OFF.

INITIAL SETTING FOR SHIPPING

1. Initialization of memories

Press STANDBY/ON button while pressing down INPUT button when the unit is POWER ON,

then the FLT displays "CLEAR", and turn to STAND-BY. Remove power cord from power line.

2. Other settings

Pull out the AC cord at the standby mode.

FIRMWARE UPDATE - 1

Arrangements for PC

Make the firmware folder under the Net-Tune Central folder.

1
2 Make the folder of a suitable name (ex.:FW_NAC23) in that.
3 Putting the following 4 files in that.

Fdist.fdf - File Distribution File

FW_0_1_0.dcf - Device Construciton File

LanY08na.mot - The program of Network microprocessor (The file name changes by the version).

LanY08rb(L).mot - The program of System microprocessor (The file name changes by the version)

4 Start Net-Tune Central.

Note!

Update initializes each setting data.

Put only the folder which puts firmware in the firmware folder. And, do not make the folder of the subordinate position from it.

When you replaces or edits the above file, you should end Net-Tune Central once, and restart. Otherwise, the change is not reflected.
